SPECIFICATION forming part of Letters Patent No. 770,410, dated September 20, 1904.

Application filed May 4, 1903. Serial No. 155,536. (No model.)

To all whom, it may con/067%:

Be it known that 1, CHARLES D. WRIGHT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Detachable and Antiseptic Mouthpieces for Telephone-Transmitters, of which the following is a specification.

This invention relates to an improved device to be used as a suppemental or auxiliary mouthpiece for telephone-transmitters; and it consists in certain peculiarities of the construction, novel arrangement, and operation of the parts thereof, as will be hereinafter more fully set forth and. specifically claimed.

As is well known, it is held by many physicians and scientists that by reason of the frequent use of telephones by different persons who speak and exhale their breath into the transmitters thereof the germs of disease are or may be transmitted from one person to another.

It is therefore one of the objects of my invention to provide an antiseptic and detachable mouthpiece which shall be quite inexpensive and so constructed and prepared or treated that it may be readily attached to the ordinary or fixed mouthpiece of the. transmitter or removed therefrom and when in use thereon will destroy disease germs or other micro-organisms by reason of its antiseptic qualities.

Another object of the invention is to so construct the mouthpiece that all or a portion of the exposed surface thereof may be utilized for the display of advertising matter.

Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which- Figure l is a perspective view of a telephone-transmitter of the ordinary or usual construction and a part of the supportingarm therefor, showing one form of my invention in place on the transmitter. Fig. 2 is a face view of the improved mouthpiece detached. Fig. 3 is a central sectional view through the ordinary mouthpiece of the transmitter, showing my detachable mouthpiece in position thereon; and Fig. 1 is a rear view thereof.

Like numerals of reference refer to corresponding parts throughout the different views of the drawings.

The reference-numeral 10 represents the fixed or ordinary mouthpiece of the transmitter 11, which maybe supported on an arm 12 of the usual construction and in the wellknown manner. The inner end of the mouthpiece 10, which is trumpet-shaped, as shown, is screw-threaded, as at 13, to engage suitable threads in an opening 14 therefor in the transmitter. Near its inner end the mouthpiece 10 is provided with a transverse partition 15, having a series of perforations 16, as usual.

The detachable mouthpiece 17, which constitutes my invention, may be made of papiermach, fiber, or any other suitable material and is formed into a hollow truncated coneshaped piece of any size to fit in the mouthpiece 10, so as to extend at its inner end to near the outer surface of the partition 15 thereof. The outer end of the piece 17 is formed with an annular retaining-flange 18, which will embrace the outer end of the piece 10 and possesses enough resiliency to cause it to yield slightly, yet to clamp the mouthpiece 10 sufficiently to securely hold the detachable piece 17 in position thereon. EX- tending laterally and at about right angles from the retaining-flange portion 18 is a display-flange 19, on the front surface of which may be printed or otherwise displayed advertising matter.

Ordinarily the detachable mouthpiece may beheld in position within the fixed mouthpiece 10 by means of frictional contact therewith and the clamping or spring-like efiect of the retaining-flange 18; but as the fixed mouthpiece 10 may not be of the same or uniform size, so as to allow the detachable mouthpiece 17 to extend therein far enough to permit the retaining flange or portion 18 to engage the outer end of the fixed mouthpiece, I

may use clips 20 to clamp the edge of the flange l9 and locate them diametrically opposite each other, as shown in Fig. 4: of the drawings. These clips when used are connected together by means of an elastic cord or band 21, which may be placed over the mouthpiece 10, as is clearly shown in Figs. 8 and 4 of the drawings, thus holding the detachable mouthpiece securely in place.

To render the detachable mouthpiece antiseptic, it may be saturated, coated, or otherwise treated with a germicide or other antiseptic substance or material.

It is apparent that the entire or a portion only of the exposed surface of the detachable mouthpiece may have displayed thereon any suitable advertising matter.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A detachable mouthpiece for telephonetransmitters, consisting of. a hollow truncated cone-shaped piece having its larger end upset to form an annular retaining-flange and a display-flange at substantially right angles to the retaining-flange, substantially as described.

2. A detachable mouthpiece for telephonetransmitters, consisting of a hollow truncated cone-shaped piece, clamps attached to the edge of the enlarged portion of said piece and diametrically opposite each other, and a cord or band uniting said clamps and adapted to embrace the fixed mouthpiece of the transmitter, substantially as described.

3. A detachable mouthpiece for telephonetransmitters, consisting of a hollow truncated cone-shaped piece having its larger end upset to form an annular retaining-flange and adisplay-flange at substantially right angles to the retaining-flange, clamps secured to the edge of the display-flange diametrically opposite each other and a cord connecting the said clamps and adapted to embrace the fixed mouthpiece of the transmitter, substantially as described.
